My daughter and I walked the Camino last summer, and we had booked our flight home out of Barcelona, thinking it would be fun to see that city while we were there. However, we were rushed in our walk, because we had a deadline to catch this flight across the country. We were tired and dirty by the end, no clean clothes, and looking back, we wished we had just flown out of Santiago at the end of the walk, as it was such a fantastic walk, that it kind of spoiled it to go to the hustle and bustle of Barcelona, so far removed from the Camino. We wish now that we had spent the extra days on the trail seeing more of the villages we rushed through. We didn't pre-book our flight from Santiago to Barcelona, however, and it was easy to book a flight. (Avoid the airline that starts with "R!" at all cost, it is a total nightmare!) (Are we allowed to say that here?) There are national travel agents in offices in many places in Santiago, you will see their signs alongside the shops on the streets, (can't remember the name of them, but just ask anyone) to help with flights and accommodations. Don't forget to go to Finesterre, -- awesome ride through the seaside villages along the way on the bus. Also, we wished we had more time in Santiago, it was fabulous, we could have spent days there.
